To all trimm it inf/ 1,1 concern:

Be it known that l, JAMES Cai/annoia, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusettshave invented certain mprovements in Machines for Use in the Manufacture of 'Boots and, Shoes, oft which the following description, in connection. with the accompanying drawings, vis a specification7 like reference characters on the draw ings indicating like parts in the several igures.

This invention .relates to machines for lasting; shoes and herein shown as em h odietl in a machine adapted to he operated in part hy hanrl and to be carried about the peripheryl ot the shoe during the lasting yoperation.

It has heen customary, in the operation of lasting` shoes. to employv hand pincers hy 'which the upper is tensioned about the last and brought into 'position over the last to he secured by driving tacks through the upper and rinsole .into the last, the tacks being'` lett upstanding, in lasting; welt shoes, so that. they may he remoretl prior to the inseamingor Weltiing; operation. Attempt has also heen marietoprovide hand pincers of 'the kintl ieierretl to with tackling mechanism more or less automatic in operation by' which the lasting; tacks were to he fell and driven after the upper had been properly7 tensionetl by' thepincers.

T he use ot lasting tacks is, of course, in itself objectionable in the toreparts ol' ivelt shoes as the tacks constitute only' temporary' tastenings fonhohling the ripper to the last while it is in temper and causing Ait to conform to the last so that when it dries ont the tacks may be partly removed Without the upper drawing away from the last to a great extent. The repeatetl driving ot the asting' tacks into the last soon destroys the ioltiing power of the wood and renders the ast* useless, necessitating the replacement of the lasts at great expense. As a usual practice the heavy lasting tacks also are removed and replaced by a smaller nnmber'of slender stay tacks before the operation of sen ing,` on the welt is performed` as the heavy lasting tacks get in the Way of the needle of the Welter and cause frequent breakage.

A general object of this invention is to improve lasting` apparatus, and more par- Specification of Letters Eatent.

. ,ticnlar objects are Yto improve apparatus by pulling' an upper over a last and means for inserting tastenings in a plane s mtantiallv parallel to the last bottom in position. to con neet the ripper tothe lip of an :insole et 'power ope ated mechanism constructed and arranged to insert astening anni thon come automatically to r i-r Further 'feature of tl e i tion conf sists .in manually operated meant n' seizing; and tensitming a portion of an upper about a l ast combined with mechanism ope connected with saitl means Afor staple horizontallv through. the ur the channel lip ot an insole. l'n l l 'tratetl embodiment oiE the invention staple inserting; inea' s power opcrateii: also the imper tenero ing means comprises hand p'i'ncers, antl a controller for the pmv l itis- 'he manipulated by the hantl, ot the operator which. manipulates the pincers.

Another Jfeature of the invention com pri. s an anvil which cooperates with liaste ing; inserting,` means to clench a t.; antl which is moved towartl the tasteinii inserting means to @lamp the channcl lip. and the upper together during the Atastening inserting' operation. As shown, the anvil is mountet ona carrier which moves it against the channel lip on 'the inner side, anti a re silient, connection is provirieti hee-:een the anvil snel its carrier so that at, tiret the anvil exerts: yielding clamping pressure and suhsequently, as the carrier continues its move ment toward the channel' lip becomes unyieltling to resist theV actionol. the driver and. cooperates therewith in clenchii'ig` the fastening.

Another feature of the invention consists in the combination with means for inserting fastenings, and means -for pulling an upper over a last, of means; for pressing together the upper and the channel lip4 of an insole, comprising means to enter the angle of union between the feather of the insole and the channel, and` for ing the upper into the loll' angle in advance of the fastening inserting operation.

Other objects and features of the nvenf tion including certain detailsof construction andnnore important combinations of parts lwill be apparent from a consideration of the following description vvhen read in conneoi y' tion with the accompanying drawings, and

will bepointed out in the claims.

In the drawing Figure 1 is a side cievation of the machine partlyin section; Fig.,2 is a perspective view, partly in section., of pertions of the stapleforming mechanism.

'The cams from which the various mech-v anisms are operated are 'connected to a main driving shaft 2 mounted in bearings in the frame or head 4. Motion is communicated to the shaft 2 from la' bevel gear 6 having a shaft 8 which may be connected to any con- .venient source of power, for example, by a flexible shaft. Preferably the machine will bel suspended from a loop 10 upheld by means i S ofa spring or counterweight to relieve uthe operator of a portion or all of vthe Weight' of the fastener forming and inserting mechanism. The bevel gear 6 meshes with a bevel gear 12 Which is loose on the shaft 2.

A sleeve 14 is ysplinedbupon the shaft 2 and carries pins 16 adapted to engage recesses in the gear 12 whereby motion is communicated from the gear 12 to the shaft The sleeve 14isheld in engagement with the `gear 12 by a spring 18 and is Withdrawn from engagement by a pin 20 acting in a groove 22 formed in the sleeve. A. trigger lever .24 carries a'spring-held plunger 26 which engages a groove in the pin 20 which is normally upheld by aspring 2S. lt VWill be seen that movement of the lever 24 will the gear 12, movement of which is' then com draw down the pin 20, :thereby releasing the sleeve 114 which, in 'response to the pressure ,I

of the spring 18, slides into engagement'with moved to the left, Fig. 1, as it rotates to cause disengagement of the pin 1 6 trom-the gear 12 and consequent stopping of the fastener inserting mechanism.

. pincers `which are pivotedat 32 tot v The framefi carries a' :toot 30, pivoted at 31 to the frame of the .machine, which is ads'ipted to rest upon the insole of ashoe and toform a ulcrum' forthe actio of the lieti-ame 4. The pincely jaws 34, .36 arepivoted to each other at-38 and areprovided with lian- 'dles 40, 42 (shown broken away in Figli), by

which they are operated. Movement of the pincers about they pivot 32 is' restricted by a pin on the machine frame which engages Licence pin .20, allowing it to fsnap- I aslot 46 formed in the pincers and curved about the pivot 32 as a center.

The fasteners driven by the iastener inserting mechanism are preferably inthe yform of staples and, for the purpose of ex emplification, mechanism is herein shown for coil of Wire.v yThe mechanism shown is con- Astriicted and arranged to drive a staple through theupper while held in tensioned.

formingsu'ch staples automatically from a condition bythe 'pincers and through the channel lip or the shoulder of the insole of -the shoe and to clench the staple upon the inside of channel. l y

rThe staple forming mechanism herein shown comprises an outside: former 542err'anged to slide ina guideway 56 in the head the channel lip or in thel inside i of 'the machine, this guidevvay being formed [preferably in Aa plate 58 which is fastened to the under side of the machine head. The outside former 54 is constructed and arranged to embrace an inside former 66 as it movesorward, and to form around the inside former a length of wire which has previously been fed into position to be acted upon by the said outside former.

The Wire which is to form a staple is preferably severed in advance of the staple -ormf 95;

ing operation, andthe illustrated means for severing the Wire comprises a cutter 68 carried by the outside former, the said cutter cooperating With a wire guide 70. The outside former is moved into coperative relation to the inside former to form a-vstaple by means operated fromr cam groove 74 in a cani block 76 on the shaft 2, said'means com prising alever 78 pivotedbetween its ends at 80 to the/ i achine frame and connected by a link 825th] the outside former '54. The groove lower sid :iso that it forms a-guiding lgroove for the stiiple .when it is'being driven and also a guiding groove for the staple driver 100. Below the enlarged lower portion of Slin the outside former which re-l ceives th inside former 66 is. enlarged at itsv the groove in the outside .former there is a l 4solid portion 86 of the outside former which closes the groove and forms a support for the staple driver 100, this portion being extended at the-front of the outside former to form a tongue 110 having a 'function hereinafter to be referred to.

The staple driver 100 is operated from a cam groove 102 in a cam 'block 104 througha lever 106 pivoted between its endsat 108 to they machine frame and connected to the driver by a link 112, as elearlyshown in 1.' A. stiiening rib 114 upon the driver 1001i is received by the groove 84 in the outside former. As the staple driver 100 is `moved forward by the connections just deL scribed to drive the staple, the inside formerl 66 ris moved up out of the way'of the driver, said inside former being carried by a bolt 92 arranged 'to slide vertically ir. a guideway 91 in the machine head, the said bolt having a reduced portion at its upper end Whichris inelosed by a sleeve -96 and carries a pin 97 which engagea slots in the sleeve 9G, the pin being held normally at the bottom of the slots by a springl within the sleeve. Shown in Fig. 1. rillu-pupper end oli the sleeve Q6 oarries a canrroll which engages a suitably formed eem ath in the rear end of the cani block 713. rlfhis cam path is shaped to raise and lower the inside former in proper time relation with the reeiproea tion of the outside former.

The forward end of the guiden'ay `tor the outside jt'orinel and 'for the staple driver ie formed as a nose 19.) vvliieh is eo shaped that it will crowd the u iper into the angle between the rib of the ineole and the projectingr feather, Without interfering with the operation of the lasting pincele. and will guide the staple in a Substantially horizon tal. direction through the upper and chair nel lip of .the insole oi' the shoe, the guidi-:- Way in said nose being in line with. the clenching end ot the staple clenoher 126 which is pivote-fl at to the lower end of a. lever or carrier 13u which pivoted bev tween its ends at 1325 to the machine :frame and at ite upper end carrie" roll which eooperates with a face orina formed on the :liront end of the cam bloeit 76. The staple clencher 126 carries; a rearward extension 136 which held against a stop 138 formed on the lever 18d by a springlill. This construction affords a yielding pressure of the staple clenoher 12C against the lever 13() to provide itin* variations .in trie thickness of `the material between the nose ot the staple forming mechanism and the ohannel engaging end of the clenehing member. The

elenehing member is normally held away from the rib the insole by a spring 142 and is moved toward the nose of the staple forming mechanism at the time the staple is driven 'by the action of the face cam 133 ou they upper end of the lever 180. The clenehing; member or anvil acts to press the upper andthe channel lip together before and during the operation ot' inserting the fastening. and. aiter the lever or carrier 130 has moved far enough to take up the yield of the spring 141-2, the anvil is held unyieldingly against the rear face of the kchannel lip to cooperate. withthe driver in olenehing the fastening.

The nose 12() of the staple former is preferably formed in two parts, a lower part which contains an extension of the guideway staple forming operation.

' the noseat the same time that it enwafes the upper and tucks it into the angle oi union .between the channel lip and the feather of the insole. The tongue 110 is tapered on its under side so that it tends to ride up over the edge of the insole as it presses the'upper into positionl to receive the staple, this movement oit the tongue serving also to more the shoe and last relatively to bring` the parts into suoli position that the staple is guided through the upper and channel lip in a line above 'the path of movement of the needle of the Welter in the Welt stitching operation. lt will be noted also that the tongue 110 has a wiping as well as a pressing or tueltinibY action as it comes forward, the upivard taper at the forward end of the tongue serving also to prevent injury to the upper as it is wiped over the corner of the.

last.

The uire 150 from Whioh the staples are to' be formed may be carried by a reel 15:2

mounted on a suitable bracket extending from the frame 4 of the machine. The Wire is fed to the staple forming meehanisinby a gripping mechanism comprising a slide 154 and acooperating link 156, mounted in ears on the slide 1.3i and havingr its upper end pivoted at 1:35a'` to the lower end Yof a lever 160 which is pivoted to the machine frame between its ends at 162 and at its upper end is connected by a curved slot and pin contention. as shown in Fig. 2, Withv a comieetin-gl rod 1G45 having a slot which einbraces the cam shaft 2 anda pin 166 which cooperates with a cam path formed in one face of the cam block 104C, Movement is thereby communicated to the lower end 'of the lever 160 which operates, When moving to the left, Fig. 2|', tiret to swing the link 156 which has a gripping edge 157 that coperates with the upperlface of the slide 154: to grip the Wire'ff `urther movement of the lever 160 carries the slide and ilv'ire forward and feeds the amountiof Wir required to form a staple to the stapleforming` mechanism. Reti-actionl of the Wire fed is prevented by a onewvay Clutch comprising the member 17() mounted in an inclined groove 172 .and held in engagement `with the Wire by a suitable spri'nff. 1t Will be obvious that this device permits the eeding of 'the wire toward vthe staple forming mechanism, but prevents movement of the wire in the opposite direction. The amount of-Wire fed to the staple forming' mechanism, and

hence the length of thev staple, may oe adjusted by changing the position of the end y of the connecting rod 164 in the slot 161 in the upper end of the lever 160'.

The machine is particularly adapted for lasting the sides ofivelt shoes but also may he' used for lasting turn shoes. in the use of the machine the shoe is supported by a suitable jack, Aand the foot 30 is restedY upon the insole of -the shoe, and the pincel-s are moved above the pivot-s 31, 2:52 to seize and tension upwardly a portion of the shoe upper. The mechanism for inserting` fastenings is lpositioned vertically and horizontally relatively to the shoe insole rhy the anvil 126 and the nozzle 120, and when the upper isproperly tensioned a trip 2l is operated to set the clutch, whereupon4 the mechanlsm.operates to press the upper and channel lip together and to clench the staple against the anvil 126. The mechanism then comes to rest, and the pincers may be released and the Inachine moved into position to enable another portion of the upper. to be similarly tensionedvand fastened.
